Fix importorskip guard and add LiteLLM_TeamTableCachedObj import

- Add pytest.importorskip("mcp") at module level so tests skip cleanly
  in CI environments without the mcp package (instead of ImportError)
- Import LiteLLM_TeamTableCachedObj into MCP_AVAILABLE block so type
  annotations resolve for static analysis and get_type_hints()
- Remove string quotes from type annotations now that the import exists
